It sounds like you needed to log one character into the wrong server and disconnect/reconnect the internet at the right time, so it seems pretty unlikely anybody banned actually did this accidentally.
There isn't really much need to rollback every innocent player if the exploited stuff is extremely traceable.
Rollbacks with live service games generally don't go over well with the players, especially the ones who did nothing wrong in the first place.
The problem with doing a rollback is that, unless you want to spend a lot of time fixing the things the rollback breaks, you have to roll EVERYTHING on the server back. This means all players will have progress reset and items lost. More players are likely to quit the game than Blizzard will lose by banning a few cheaters.
